Greek Pork Tenderloin with Spinach and Feta Cheese

During my early days in London, I lived in a tiny mews apartment. above a garage. The small kitchen called for “minimalist” cooking. Workspace was confined to a chopping board that I would lay on top of  the sink.

Recipes had to have few pans to clean, few ingredients to prep and a limited time in the kitchen because it got so hot and steamy.

One of the dishes I relied on for foolproof and space saving entertaining was grilled pork tenderloins served with very finely chopped garlic and fresh rosemary with separate drizzles of lemon juice and olive oil. I still use this simple approach when I want a tasty, no fuss dish in under 20 minutes.

Since then, I tried more elaborate recipes that usually involved various concoctions made with apples, cherries, cranberries, apricots or maple syrup. I never really liked them.

So here is a welcome change from those traditional recipes. Juicy tender pork tenderloin filled with a blend of spinach and creamy feta cheese flavored with fresh mint and nutmeg and basted in a tangy balsamic and rosemary sauce.

An absolutely delicious combination that will convert diehards who are not fans of pork or bored with traditional recipes.

Equipment

  • 8" frying pan
  • baking tray
  • cooking twine

Ingredients
  

  • A 1 lb pork tenderloin (one loin usually serves 2-3 people)

For The filling

  • 1 tbsp olive oil
  • 1 medium sized yellow onion, finely chopped.
  • 4 cloves of garlic, finely chopped
  • 1 tsp nutmeg
  • 1 ½ tsp dried oregano
  • 2 cups fresh baby spinach
  • ½ cup fresh mint leaves (or 2 tsp dry mint)
  • zest of one lemon (divided)
  • cup feta cheese cut into 1" chunks (for the creamiest result, use feta that has been packed in brine).
  • salt and red pepper flakes to taste

For the basting mixture

  • cup balsamic vinegar
  • 1 tbsp olive oil
  • 1 tsp dijon mustard
  • 2 tbsp chopped rosemary
  • 3 cloves garlic, grated
  • 1 tsp lemon zest
  • 1 tsp ground black pepper
  • salt to taste

Instructions
 

  • Preheat the oven to 425 F degrees (220C)

For the filling

  • Heat the oil in a small skillet over medium/low heat. Add the onions and cook till translucent - about 3 minutes. Add nutmeg, oregano, grated garlic and a pinch of red pepper flakes into the oil. Saute until fragrant, about 30 seconds. Add the spinach and mint and allow them to wilt, about 2-3 minutes. Sprinkle lightly with salt, mix and remove the mixture from the heat.
  • Place the spinach mixture on a chopping board and coarsely chop the mixture. Mix in half the lemon zest then fold feta cheese with a cooking knife into the mixture. Keep some chunks of feta large. Set stuffing aside.

For the basting mixture

  • Combine balsamic, oil, mustard, rosemary, lemon zest, garlic, salt, and pepper in a small bowl and whisk until smooth. Set aside.

Prep the tenderloin

  • Place the tenderloin on a cutting board board and trim any remaining excess fat or tendons with a small sharp knife. Slice along the length just deep enough to butterfly it. Do not slice it too deep in case you pierce through the tenderloin.
  • Place a plastic sheet on the tenderloin and flatten it with a mallet or small frying pan till it is about 1/4 inch thick.
  • Spread the stuffing mix along the center but do not overstuff.
  • Roll the tenderloin over the stuffing and tuck in the sides as you roll it.
  • Tightly tie the tenderloin with cooking twine in four or five places about 2” apart so it holds its shape and the stuffing while it roasts.
  • Line a roasting pan with parchment paper so that the basting liquid does not caramelize. Place the pork loin on that with the knots of string facing down. Smear all sides with the basting mixture. Use all the mixture because you will use it as a sauce once it is cooked. The balsamic vinegar mellows out and with the rosemary and garlic makes a delicious sauce.
    Baste occasionally while the pork is roasting.

Roast the tenderloin

  • Roast the tenderloin for 15 minutes at 425F (220C) then reduce heat to 375F (190C)and roast for an additional 10 minutes or until a thermometer inserted in the thickest part of the loin reads at least 145F (63C). Allow the pork to rest for 10 minutes.
  • Cut off the ties, slice the tenderloin into 1”thick slices and serve with a little of the cooked basting liquid.

Notes

Tenderloins vary in weight but usually come in 1-11/2 lb weights. The smaller 1lb tenderloins can easily serve 2-3 people and you may need the larger weight for 4 people with some leftovers. 
Leftovers can be reheated in a low, 250F (120C) oven.
Like lamb, pork is usually served pink so it remains juicy. In fact the USDA Food Safety and Inspection Service found that cooking pork to a temperature of 145F (63C) and letting it rest for three minutes is safe although it may still look pink.
